Are 6 and 11 relatively prime numbers?
Yes.
What are co-prime numbers?
Relatively prime. In mathematics, the integers a and b are said to be co-prime or relatively prime if they have no common positive factor other than 1 or, equivalently, if their greatest common divisor is 1. for example 6 and 35 are co-prime. (neither is prime) 6 has the prime factors of 2 & 3, 35 has the factors 5 & 7.
What are all the prime numbers from 1-6?
The prime numbers from 1 to 6 are 2, 3 and 5.
I need to know which pair of numbers in relatively prime 10 and 21 or 12 and 54 or 15 and 27 or 21 and 38?
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
Is 30 a relatively prime number?
A number cannot be relatively prime number by itself. It can only be relatively prime in the context of (relativeto) another number. That requires the two numbers not to have any prime factors in common.
